Drilling a nano

[sphelps]

The smaller the tank the harder it is to drill. I have some glass hole saws if someone in Calgary wants to borrow one, can't guarantee I'll have the size you want but I have a few sizes available. However if it's your first time drilling glass and you're doing a nano with 3mm glass I give you a 50/50 chance of success

I havent used that brand per se, but I have used lifereef and similar utube based models...

Properly set up, there is no difference between one of these and a drilled overflow.

I have used both systems before and as some of you may know from previous threads, am a utube overflow advocate.
